Ingredients

The beauty of this recipe is its simplicity. You likely have most of these items in your pantry right now.

For the Brownies:

• Strawberry Cake Mix (1 box, approx. 15.25 oz): This is the base. Brands like Duncan Hines, Betty Crocker, or Pillsbury work perfectly. Do not follow the instructions on the back of the box!
• Eggs (2 large): These provide structure. Using only two eggs instead of the usual three found in cake recipes helps ensure the result is dense like a brownie rather than fluffy like a cake.
• Vegetable Oil (1/3 cup): You can also use canola oil or melted unsalted butter. Oil tends to make the brownies slightly moister, while butter adds a richer flavor.

For the Glaze:

• Powdered Sugar (1 cup): Also known as confectioners’ sugar. This creates the smooth, sweet finish.
• Water or Milk (1/2 to 2 Tablespoons): Milk makes the glaze creamier and more opaque, while water creates a simpler, more translucent glaze. Both work beautifully.

Instructions

Follow these step-by-step instructions to achieve the perfect fudgy consistency.

1. Preheat and Prep:
   Preheat your oven to 350°F (175°C). Line a 9×13 baking pan with parchment paper. Tip: Leaving an overhang of parchment paper makes it incredibly easy to lift the entire block of brownies out of the pan for easier cutting later. If you don’t have parchment, grease the pan generously.
2. Mix the Batter:
   In a large mixing bowl, combine the dry strawberry cake mix, 2 eggs, and 1/3 cup of oil. Mix by hand or with an electric mixer until well combined. The batter will be very thick and sticky—much thicker than normal cake batter. This is normal! Do not add water.
3. Spread in Pan:
   Transfer the thick batter into your prepared baking pan. Because the batter is sticky, it won’t flow on its own. Use a silicone spatula or offset spatula to press and spread it evenly into the corners. Pro-Tip: If it’s sticking to your spatula, lightly spray the spatula with non-stick cooking spray.
4. Bake:
   Bake at 350°F for 15 minutes. This is the most critical step. You want to bake them until the center is just set. Do not wait for the edges to brown significantly. They might look slightly underdone in the middle, but they will firm up as they cool. Overbaking leads to dry brownies.
5. Make the Glaze:
   While the brownies are baking (or immediately after pulling them out), whisk together the 1 cup of powdered sugar and water/milk in a small bowl. Start with 1 tablespoon of liquid and add more slowly until you reach a smooth, pourable consistency.
6. Glaze and Cool:
   Pour the glaze over the brownies while they are still hot/warm. Use a spatula to spread the glaze to the edges, allowing it to drip down the sides. Glazing while hot helps the icing set into a thin, crackly layer rather than a thick frosting.
7. Set and Serve:
   Allow the brownies to cool completely in the pan. The glaze needs time to set. Once cool, lift them out using the parchment paper and cut into squares.

Tips for the Perfect Fudgy Texture

Getting that dense, chewy texture is the goal of this recipe. Here are expert tips to ensure success:

• Do Not Follow Box Directions: Ignore the water, oil, and egg quantities listed on the back of the cake mix box. Only use the quantities listed in this recipe (2 eggs, 1/3 cup oil).
• Watch the Oven: All ovens vary slightly. Start checking at the 12-minute mark. If you insert a toothpick, it should come out with a few moist crumbs, not wet batter, but definitely not clean. Clean means dry!
• Room Temperature Ingredients: Using room temperature eggs helps the batter emulsify better, leading to a more uniform texture.
• Glazing Temperature: Glazing while the brownies are hot creates a “glazed donut” effect where some of the sugar melts into the crust. If you prefer a thick, white frosting layer, wait until the brownies are completely cool before glazing (and use slightly less liquid).

Creative Variations

Once you master the base recipe, try these fun twists:

• Lemon Strawberry Brownies: Use lemon juice instead of water/milk in the glaze for a tart, pink-lemonade flavor profile.
• White Chocolate Chip: Fold in 1/2 cup of white chocolate chips into the batter before baking. The creamy chocolate pairs beautifully with the artificial strawberry flavor.
• Cream Cheese Frosting: Skip the glaze and top cooled brownies with a tangy cream cheese frosting for a richer, more cake-like dessert.
• Fresh Fruit: Press sliced fresh strawberries into the top of the batter before baking. Note that this adds moisture, so you may need to bake for an extra 2-3 minutes.

Storage and Freezing

These brownies stay incredibly moist if stored correctly.

• Room Temperature: Store in an airtight container for up to 3-4 days. Placing a slice of white bread in the container can help keep them soft.
• Refrigerator: You can refrigerate them for up to a week, but they are best served at room temperature to maintain that gooey texture.
• Freezing: These freeze beautifully! Cut them into squares and wrap individual brownies in plastic wrap, then place them in a freezer-safe bag. They will last for up to 3 months. Thaw on the counter for an hour before eating.

The Science Behind the “Cake Mix Hack”

You might wonder, “How does a cake mix become a brownie?” The answer lies in the hydration. A standard cake recipe calls for water (usually a cup) and 3 eggs. This high liquid content creates steam and activates the gluten in a way that creates a fluffy, aerated crumb structure.

By eliminating the water entirely and reducing the eggs to two, we are drastically lowering the hydration. This prevents the flour proteins from fully developing into a sponge-like network and prevents the leavening agents (baking powder/soda in the mix) from lifting the batter as high. The result is a collapsed, dense structure that relies on the fat (oil) and sugar to provide that irresistible fudgy mouthfeel.

FAQs

Q: Can I use butter instead of oil?
A: Yes! Melted butter works as a 1:1 substitute. It adds a delicious savory note, though the texture might be slightly firmer when cooled compared to oil.

Q: My batter is too thick to mix, what did I do wrong?
A: You likely did nothing wrong! The batter is supposed to be extremely thick, almost like cookie dough. Resist the urge to add water. Just keep mixing; the eggs and oil will eventually hydrate the dry mix.

Q: Can I double the recipe?
A: Absolutely. If doubling, bake in a larger pan (like a jelly roll pan) or two 9×13 pans. Watch the baking time carefully.

Q: Why did my brownies sink in the middle?
A: A slight sink is actually desirable for that dense texture! However, if they sank drastically, they may have been underbaked. Remember, we want “gooey,” not “raw.”

Serving Suggestions

While these are perfect on their own, you can elevate them for a dinner party:

• The Sundae: Serve a warm square topped with a scoop of vanilla bean ice cream and a drizzle of strawberry sauce.
• Tea Time: Cut them into smaller, bite-sized triangles and serve alongside Earl Grey or chamomile tea.
• Gift Giving: These stack well and don’t crumble easily, making them perfect for gifting in cellophane bags tied with a ribbon.

Enjoy making these delightful Strawberry Brownies! They are the proof that sometimes the best recipes are the simplest ones.
